CPU Freq problem FC6

[Frank Pineau]

I have a P4 notebook (Compaq NX9010-Pavilion ze8500) with which I'm
having CPU frequency problems.  It's a 2.8GHz processor, but I can't
seem to get it above 692MHz.

speedstep-smi: you're trying to use this cpufreq driver on a Pentium 4-based CPU. Most
likely it will not work.
ACPI: CPU0 (power states: C1[C1] C2[C2])

Note the speedstep-smi line.  

I've tried disabling cpuspeed and also tried manually selecting frequency.

Personally, I'd prefer to have scaling working only on battery power, but I'll
settle for getting it to work *at all*.

Any suggestions?

This is bz 204477. Already fixed in CVS, will go out in the next update.

It's not actually changing your CPU speed, but exporting complete nonsense
to userspace.

Looking at your CPU flags..

You lack 'est' (speedstep), so you're out of luck.

That's cool.  I can deal without having speedstep if it means I get my
missing 2.2GHz.  I wonder at the timing, though.  I seem to recall
seeing this under FC5, too, but never did anything about it.  How long
has this been a problem for me?  I've been running Core on this laptop
since FC1.  Surely I haven't been crippled this long?  (Or am I just
misunderstanding, that it's actually running at 2.8Ghz, but reporting
692Mhz?)

I think that is the case. You should be able to confirm it with
x86info --mhz

try 

#kill -s SIGUSR1 xxxx 
xxxx is to be replaced with the pid of cpuspeed. 

#ps ax | grep cpuspeed

I had to manually start cpuspeed because for some reason it wouldn't
start (even though it said it had) from s-c-s.

#cpuspeed -d
